Spheeria subvestita, K- & E. Journ. Mycol. II, p. 100. 

 Zignoella subvestita, Sacc. Syll. 7495. 



Perithecia seated on the bare wood or on the bark, with the base 

 sunk in the matrix, ovate-conical, 165-250 // diam., J mm. or more 

 high, black, rough, excc-pt the smooth, subshining, short-cylindrical or 

 suliconical, broadly perforated, subtruncate ostiolum. Asci clavate- 

 c\ lindrical. 50x6-7 JJL, with filiform paraphyscs mid a slender, stipitate 

 base. Sporidia fusiform, yellowish-hyaline, slightly curved. 3-septate 

 and constricted slightly al the middle septum, 12-15x2-3 //, crowded - 

 biseriate. The spoi-idia are much the same as in Clypeosphceria II cn- 

 dersoniw. KI1.. except in having the ends slightly curved, hut in that 

 species, the perithecia an 1 depressed, subcuticular and subastomous. 

 Ziynoetta <-on'n-(i, (Fckl.). has much larger sporidia (28x4 //).

FAMILY. CERATOSTOMEJ1. 



Stroma none. Perithecia superficial, or at first immersed and 

 finally erumpent, with an awl-shaped or at least more or less elongated 

 ostiolum. Texture thin-membranaceous, or sometimes subcoriaccous. 

 Asci mostly very evanescent, with the membrane thickened at the apex. 

 Paraphyses generally present. 



The most obvious character of this family is the elongated (subu- 

 late, cylindrical or conical) ostiolum. It is distinguished from the 

 Gnomo niece by the superficial or erumpent perithecia, and the presence 

 of paraphyses. 



Ceratostoma, Fr. Obs. II, p. 340. 



Perithecia more or less superficial, with a distinct, and generally, 

 strongly developed beak: substance firm, coriaceous or carbonaceous.
